摘要: Miscibility and phase separation behaviour in blends of isotactic polypropylene (iPP) ethylene-propylene diene terpolymer (EPDM, ethylene content 70%) have been examined by means depolarized light scattering, polarizing optical microscopy, differential scanning calorimetry dynamic mechanical methods. A cloud point diagram was established scattering after eliminating the influence iPP crystal melting on liquid-liquid iPP/EPDM blends. lower critical solution temperature (LCST) observed above crystallization temperature, but below iPP. This LCST is thermally reversible, so long as does not occur its vicinity. The coupling between has examined. Crystallization-induced morphology development during investigated.
